it will'be seen that the amount of heat generated in the Hoet chamber may he regulated by cutting' out or including in the circuit part of the resistance. elemente. The resistance elements aigre mounted inside the float chamber and preferably in the iuel to be heated, so that tl'iere is a minimum loss of electrical energy in heating the t'uel.

ll here found by actuel experiment that the fuel can be thoroughly heated with if'ery little current. The circuit is automatically cut off if the fuel should iter any reason cease to flow. v

l consider it au advantage to place the resistance elements vithiu. the fuel cheminer ou account o1 the 'feet that this makes por# sible to heat the fuel with considerably less current than is the cese Where the heating elements placed out-eide the i'uel chamber. Below the resistance elements a frame of insulating material it may be noted that gaeoleiie aud similar oils are non-coudueters.

While the elements are placed in au or Inary float chamber they may he placed in en eil reservoir or the lute having e Hoet elity of resie weitet/e or other automatic switch.
